KDE 3.1 Compilation Requirements
Compilers
Compiler Requirements. KDE is designed to be cross-platform and hence to compile with a large variety of GNU/Linux - UNIX compilers. However, KDE is advancing very rapidly and the ability of native compilers on various UNIX systems to compile KDE depends on users of those systems reporting compile problems to the responsible developers.
In addition, C++ support by gcc/egcs, the most popular KDE compiler, has been advancing rapidly, and has also recently undergone a major redesign. As a result, KDE will not compile properly with older versions of gcc or most newer releases.
In particular, gcc versions earlier than gcc-2.95, such as egcs-1.1.2 or gcc-2.7.2, may not properly compile some components of KDE 3.1. In addition, some components of KDE 3.1, such as aRts, generally will not compile with unpatched CVS versions of gcc 3.1.x While there have been reports of successful KDE compilations with the so-called gcc-2.96 and gcc-3.1 (cvs), the KDE project at this time continues to recommend the use of gcc-2.95-* or a version of gcc which shipped with a stable Linux distribution and which was used successfully to compile a stable KDE for that distribution.
